Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy
Wenwen Zuo, Hengxiao Guo, Jingbo Sun +25
To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, mul…
Estimating AGN Black Hole Masses via Continuum Reverberation Mapping in the Era of LSST
Shu Wang, Hengxiao Guo, Jong-Hak Woo
Spectroscopic reverberation mapping (RM) is a direct approach widely used to estimate the mass of black holes (BHs) in active galactic nuclei (AGNs). However, it is very time consu…
AGN Continuum Reverberation Mapping Based on Zwicky Transient Facility Light Curves
Hengxiao Guo, Aaron J. Barth, Shu Wang
We perform a systematic survey of active galactic nucleus (AGN) continuum lags using 3 day cadence -band light curves from the Zwicky Transient Facility. We select a sam…
High-redshift Extreme Variability Quasars from Sloan Digital Sky Survey Multi-Epoch Spectroscopy
Hengxiao Guo, Jiacheng Peng, Kaiwen Zhang +9
We perform a systematic search for high-redshift ( 1.5) extreme variability quasars (EVQs) using repeat spectra from the Sixteenth Data Release of Sloan Digital Sky Survey, wh…
The Sloan Digital Sky Survey Reverberation Mapping Project: How Broad Emission Line Widths Change When Luminosity Changes
Shu Wang, Yue Shen, Linhua Jiang +13
Quasar broad emission lines are largely powered by photoionization from the accretion continuum. Increased central luminosity will enhance line emissivity in more distant clouds, l…
Discovery of A Mg II Changing-look AGN and its Implications for a Unification Sequence of Changing-look AGNs
Hengxiao Guo, Mouyuan Sun, Xin Liu +5
Changing-Look (CL) is a rare phenomenon of Active Galactic Nuclei (AGNs) that exhibit emerging or disappearing broad lines accompanied by continuum variations on astrophysically sh…
